Question

The table shows the proportional relationship y=kx. Which is the unit rate,k?
Pls help

Answer 1

`k=(4)/(7)`

Explanation:

The equation
`y=kx` represents a proportional relationship that always passes through the origin. Excluding of the origin, you can plug any
`(x,y)` coordinate into this function to get
`k`.

Using the first coordinate, we have:

`4=k(7),\\k=(4)/(7)`

Verify that
`y=kx` works for the other coordinates
`\checkmark`

Thus, the value of constant
`k` is
`\fbox{$(4)/(7)$}`.
